The enhanced eFHS app for cardiovascular health monitoring was rated positively (4.2 out of 5 stars) and achieved high survey completion rates (86% at baseline, 50% at 3 months).

Does a mobile system for cardiovascular health monitoring demonstrate good usability and survey completion rates in Framingham Heart Study participants?
A mobile health monitoring system deployed in the Framingham Heart Study showed high usability and acceptable survey completion rates, offering a feasible tool for remote cardiovascular data collection.
Background: The electronic Framingham Heart Study (eFHS) is an ongoing nested study, which includes FHS study participants, examining associations between health data from mobile devices with cardiovascular risk factors and disease. Objective: To describe application (app) design, report user characteristics, and describe usability and survey response rates. Methods: Eligible FHS participants were consented and offered a smartwatch (Apple Watch), a digital blood pressure (BP) cuff, and the eFHS smartphone app for administering surveys remotely. We assessed usability of the new app using 2 domains (functionality, aesthetics) of the Mobile App Rating Scale (MARS) and assessed survey completion rates at baseline and 3 months. Results: A total of 196 participants were recruited using the enhanced eFHS app. Of these, 97 (49.5%) completed the MARS instrument. Average age of participants was 53 ± 9 years, 51.5% were women, and 93.8% were white. Eighty-six percent of participants completed at least 1 measure on the baseline survey, and 50% completed the 3-month assessment. Overall subjective score of the app was 4.2 ± 0.7 on a scale from 1 to 5 stars. Of those who shared their health data with others, 46% shared their BP and 7.7% shared their physical activity with a health care provider. Conclusion: Participants rated the new, enhanced eFHS app positively overall. Mobile app survey completion rates were high, consistent with positive in-app ratings from participants. These mobile data collection modalities offer clinicians new opportunities to engage in conversations about health behaviors.
Ding et al. (Wed,) conducted a observational in Cardiovascular risk factors and disease (n=196). eFHS smartphone app, smartwatch, and digital BP cuff was evaluated on Usability (MARS score) and survey completion rates at baseline and 3 months. The enhanced eFHS app for cardiovascular health monitoring was rated positively (4.2 out of 5 stars) and achieved high survey completion rates (86% at baseline, 50% at 3 months).
